How do I find my EPC rating?

An Energy Performance Certificate (EPC) is a government-issued rating of how energy-efficient a home is, from A (most efficient) to G (least). Most UK homes already have one from when they were last sold or rented.

Why it matters

• Selling: required by law before marketing a property.
• Letting: required, and from April 2028 most properties must be EPC C or above to be let.
• Grants: many energy-efficiency grants (ECO4, BUS) have minimum or maximum EPC requirements.
• Mortgages: "green mortgages" with discounted rates exist for EPC A/B properties.

My property has no EPC, or the EPC is out of date

An EPC lasts 10 years. If yours has expired (or never existed), you need a new one before selling, letting, or applying for most grants. EPCs are produced by Domestic Energy Assessors (DEAs) and typically cost £60-£100. The Verify Credentials tool in Retrofit mode helps you find a registered DEA.

My EPC underrates my home

Common. Many EPCs are produced quickly and miss recent improvements (new boiler, double-glazing, insulation). Producing a new one with up-to-date information often raises the rating by 1-2 bands. Worth doing if you are close to a band threshold and the upgrade matters for selling, letting or grants.
